Question

7. The probability of the sample space
is always equal to?
0.5
1
0.75
0.4​

Answer 1

Answer:

1.

The probability of an event is written P(A), and describes the long-run relative frequency of the event. The first two basic rules of probability are the following: Rule 1: Any probability P(A) is a number between 0 and 1 (0 < P(A) < 1). Rule 2: The probability of the sample space S is equal to 1 (P(S) = 1).
